With the MAG 100 rnd. midcaps I had some feeding issues so I took a deburring tool out of my toolbox and opened up the hole in the mag well slightly and now they feed like a dream. It's not gonna matter soon anyways as I have 10 STAR 30 rnd. realcaps coming in soon but I thought I with share this little tidbit of info.

Does anyone know what brand of selector plate will fit on the gearbox correctly? I recently snapped mine, and after trying a systema selector plate, it turned out to be too thick to fit in the receiver comfortably.

From experience we tried the Classic Army and King Arms both were too thick. I believe that the only one that fit and the one I used was a KWA one.

hi guys. what 3rd party gb can fit a kwa lower receiver? I tried a TM gb and its hard to fit in and hard to take out also. the slots for the pins wont match so I cant close the upper and lower receiver. The gb or receiver needs some modification for it to fit perfectly.
